DD750 review

Glad you like your purchased and are pleased you made it Leo!

The case is pretty handy to have - I have the lesser version of the DD - I can't remember how much I paid - it wasn't a whole lot - but, no case. Which - ok is fine, but honestly - I have to find a place to put it loose, and I don't like that. I like cases and places for everything.

Thanks for the pics too!

Pret-ty COOOl...

Can you get finer wheels for it? Are they totally proprietary or can you get (I know you'll cringe at this) "good" Norton wheels?

I kinda' wondered if it'd replicate the split point - that one I doubted pretty hard; it's a tall order to grind a split point on there. Even a decent common winged point, thought, is better than a broken drill bit & an ache in the pizzer, ain't it?

Love mine... I am pretty sure it paid for itself after a while... especially considering I never sent my bits out.. just hand sharpened them until they totally sucked then pitched them.. and bought a new bit..

One of the better investments I ever made... and honestly don't think I would have been able to make pens from acrylic without it.. gotta have a real sharp bit for those or they heat up and crack...

Actually the wheels are pretty good. Diamond.

They are 180 grit - which is the standard grit - but you can get 100 grit. I got an extra 180 and I got a 100.

It does an OK job. I can certainly live with it. The quality has to do with the holding of the bit into the machine by hand, and the motion ot the bit against the wheel. In a industrial drill sharpening machine the motions, and the design of the machine, and the shape of the wheel(S) is different. BUT, a professional drill sharpening machine is 10's of thousands of dollars.

For a small shop, and for the home shop - this is one nice little machine,

Tim - If Diane and I go fer a drive to VT in the fall, I will bring it with me. I think you will like it.

Oh yeah - I bet splitting the point makes a WORLD of diference on those. I would think on other real hard blanks too. I know the thick web and large chisel point puts a lot of pressure and hakes heat. Now I cant wait to try some other stuff,

Cool! I even have a couple bits we could futz with. I don't break 'em very often, but once in a while I get a spectacular crack outta' one. :)

EDIT: If you remember to... toss that twisted carbide reamer into the 'hicle with ya, too - I didn't get a look at that.

Leo,
Even the lesser Drill Doctors will do a split point. Read the instructions and do the alignment CAREFULLY or the split point system will hit the edge on the lips. (The regular edge) If you align the drill properly the DD will do a pretty good split point. It takes some practice but the results are worth it.

Wheel, doggy,

I got it.

Last night I watched the DVD - with the DD on my desk in fromt of me.

The DVD at explaning how to use it - in detail. Simply Great.

So I got a 3/16 cobalt parabolic flute split point 135 degree drill that I mabe badly dull. This morning I sharpened it and drilled a couple of holes.

I drilled a chunck of 6061-T6 aluminum about an inch thick - sweet
I drill a couple of holes in Oak - OK

Now - I am very very very fussy about high quality expensive cuttig tools. I have sent out literrally TONS of drills to be resharpened. I can tell a high quality resharp from a cheap resharp - at a glance.

The DD is $159, with case, extra wheel, and coarse wheel. The plastic case has specific containment for the extra wheels. I thought that was real nice.

When I ordered it - I didn't think I really cared about the case - bu I am glad I have it. I like storing all my have tools in the cabinet in their respective cases. This drill sharpener definately falls into that category. The case is nice.

I need to resharpen a 3/4 inch drill. That sells for $20.00 at borg. So - without batting an eye the DD save my spency 3/16 drill and a $20 3/4 drill.

It does an OK job at sharpening. It works. You take a drill that was going to be thrown out and you can resharpen it to a point where it will work. NO - is will NOT put a professional point back on the drill, but it WILL make a non-usable drill, usable.

So - Am I glad I have it = yes

Would I do it again - knowing what I now know = yes.

Overall - nice little drill sharpener!
